K.2 Firmware

QSC K.2 Series™ Firmware Update necessary for all customers:

When played at excessive levels with audible distortion, K10.2 models may experience a critical low frequency driver failure with no amplifier protection to alert the user. The unit may also overheat, with the potential to damage the rest of the loudspeaker. This issue is remedied by updating the firmware from version 1.0.8 or 1.1.0 to version 1.2.0. With this update, if a failure occurs the amplifier will power off voltage to both drivers and allow the user to complete a listening test to determine if the loudspeaker requires service.

Owners of K10.2 loudspeakers MUSTcheck their firmware version and, if necessary, install the firmware update. Owners of K12.2 and K8.2 will also benefit from amplifier protection improvements in the new firmware, and are encouraged to update their loudspeakers as well.
